LOCKING DEVICE.

lSPECI'EICA'IION forming part of Letters` Patent No. 632,232, dated September 5, 1899.

Application filed March 7,1899. Serial No. 708,066. (No model.)

T0 @ZZ whom it may concern:

Be it known that l, ANDREW S. BROWN, a citizen of Ithe United States, residing at New York, (Brooklym) in the county of Kings and State of NewYork, haveinvented certain new and useful Improvements in Locking Devices for Shafts, of which the following is a full and complete specification, such as will enable those skilled in the art to which it appertains to make and use the same.

This invention relates to steering and locking devices for the shafts of fire-trucks, motor-vehicles, and other vehicles, also for lever- Shafts of various kinds and classes, and steering or guiding shaftsin ger eral; and the object thereof is to provide an improved device of this class by means of Which such shafts may be turned when necessary or desirable and locked in any desired position, afurther object being to provide a deviceof the class described Which may be applied to the rudders of vessels for turning the same and holding them in any desired position. i

The invention is fully disclosed in the following specification, of Which the accompanying drawings form a part, in Which- Figure l is a sectional side view of an apparatus embodying my invention; Fig. 2, a plan View of a detail thereof; Fig. 3, a side View; Fig. 4., a view similar to Fig. 1, showing a modified form of construction; Fig. 5, a side view of a detail thereof; Fig. (i, a View at right angles to Fig. 5, and Fig. '7 a side view of a locking-bolt which I employ.

In the drawings forming part of this specification' the separate parts of my improvement are designated by letters of reference, and in the practice of myinvention, reference being made to Figs. l to 3, inclusive, I provide a support A, through which is vertically passed a guide or steering shaft B. The upper portion of the support A is reduced in size, as shown at a, and mounted thereon is a ring C, which is preferably provided With a depending flange C2 and an upwardly-directed flange C3, the opposite sides of which are formed into cam-surfaces C4, and the ring C is preferably provided with a rim O5, which is connected therewith by radial spokes O5, and by which the ring C is manipulated in the operation of the device, as hereinafter described.

Mounted on the upper end of the shaft B l is a cylindricalhead D, Which is keyed thereto, as shown at d, and provided with a downwardly-directed hub D', ivhich closely fits the shaft B, and in the opposite sides of said headare formed sockets d2, which open downyvvardly and in each of which is mounted a spiral spring cl3 and a locking-bolt d4.

Arranged in a circle on the top of the support A are upwardly-directed lugs or projections az, six of which are shown in Fig. 2, and the locking-bolts d4 pass downwardly between the hub D and the fiange Cs of the ring C, and the lower ends thereof are beveled, as shown and said lock-bolts operate in connection With said lugs or projections, as hereinafter described.

Each of the locking-bolts d4 is provided with an outwardly-directed pin d, and the head D is provided at its lowerend and on the opposite sides thereof with lugs or projections dT, and the flange C3 is provided on the side thereof and at the highest point of the cam-surfaces C4 withA an upwardly-directed point or projection C7, Which operates in connection With said lugs or projections (Z7. The operation of this form of construction is as follows: It Will be understood that the shaft B, in the form of construction shown in Figs. l to 3, inclusive, is manipulated entirely by the ring C, and theV ring Gis manipulated by the rim C5 thereof. The ring C may be turned through almost a half-revolution in either, direction, and in this operation the shaft B maybe also turned in either direction. One of the locking-bolts d4, in the position of the ring C shown in Fig. l, and also when said ring is in the opposite position, is raised and the other lowered, and in this position the shaft may be turned in one direction, the beveled portion d5 at the lower end of the locking-bolts permitting one of said bolts to move over the upwardly-directed lugs or projections a2, While the other is raised above said lugs or projections. It will therefore be seen that by means of the construction shown in Figs. 1 to 3, inclusive, the shaft B may be turned in either direction and locked in position.

In the construction shown in Figs. 4 to 6, inclusive, I have shown a support G, and a `at d5, one of said bolts being shown in Fig. 7,

IOO

shaft H passing transversely through the top thereof, and the support G is provided on the opposite sides of said shaft with sockets g, in which are mounted lockingbolts g2 and springs g3, which operate to force said bolts outwardly. In this form of construction the shaft II is provided with a cylindrical head h, having on the end thereof adjacent to the support G lugs or projections 7a2, which are arranged in a circle similar to the lugs or projections a2, (shown in Fig. 2,) and the ends g4 of the locking-bolts g2 are beveled the same as in the construction shown in Fig. l, and said ends of said bolts operate in connection with the lugs or projections h2. In this form of construction I employa ring K, which takes the place of the ring C (shown in Fig. l) and is provided on one side with a handle 7c, and the opposite sides of said ring in the direction of the support G are formed into camsurfaces 7a2. In this form of construction the lockingbolts g2 are provid ed with pins g5, which move in slots g, formed in a hub g7, formed on the support Gr, and the locking-bolts g2 move freely in said hub, While the head 7L is keyed to or formed integrally with the shaft II, and the ring K is adapted to turn freely on the hub g'f through almost one-half of a revolution in either direction. The hub Q7 or the support G adjacent thereto is provided at one side With a lug or projection 7a3, and the ring K, at the highest point between the cam-su rfaces 7t2, is provided With a point or projection 7c3, which operates, in connection with the lug or projection 7b3, to limit the movement of the ring K. In this form of construction the pins g5 on the locking-bolts g2move over the camsurfaces k2 of the ring K, and said ring K is free to turn through a partial revolution the same as in the construction shown in Fig. l, and the shaft IfI may be turned or operated by any desired means and may be locked in any desired position by turning the ring K. One of the locking-bolts g2 is free to move over the lugs or projections h2 on the head II When said shaft turns in one direction; but the opposite bolt strikes said lugs or projections and stops the shaft as the ring K is manipulated. In the position of the ring g3 shown in Fig'. 4 the shaft may be turned in one direction, but cannot turn in the other, and by reversing the position of said ring the movement of the shaft may be reversed. r

In each of the forms of construction herein shown and described it Will be seen that I employ a support, a shaft passing therethrough and provided with a head, said support and said head being provided one with spring-operated locking-bolts and the other With lugs or projections in connection with which said bolts operate and a cam-ring which operates to move said bolts against the tension of the springs by which they are operated.

The lower ends of the lockingfbolts d5 in both forms of construction herein shown and described are both beveled on the same side, so that the straight side ot' one of said bolts Will come in engagement with the lugs or projections in connection With which they operate When the ring by Which said bolts are operated is turned in either direction.

Having fully described my invention, I claim as new and desire to secure by Letters Patent- 1. In adevice of the class described, asupport, a shaft passing therethrough and provided with a head, said support and said head being provided one with aplurality of springoperated locking-bolts, and the other with lugs or projections in connection with which said bolts operate, and a cam-ring adapted to turn on said support and to move said bolts against the tension of the springs by which they are operated, substantially as shown and described.

2. In a device of the class described, a support,a shaft passing therethrough and prov-ided with a cylindrical head, said support and said head being provided one with lugs or projections, and the other with spring-operated bolts which operate in connection With said lugs or projections, the ends of said bolts which operate in connection With said lugs or projections being beveled on opposite sides, and means for moving said bolts against the tension of the springs by which they are operated, substantially as shown and described.

3. In a device of the `class described, a support, a shaft passing therethrough and provided With a cylindrical head, said support and said head being provided one With lugs or projections, and the other with spring-operated bolts which operate in connection with said lugs or projections, the ends of said bolts which operate in connection With said lugs or projections being beveled on opposite sides, and means for moving said bolts against the tension ot' the springs by which they are operated, consisting of a cam-ring mounted on said support and adapted to turn thereon,snb stantially as shown and described.

In testimony that I claim the foregoing as my invention I have signed my name, in presence of the subscribing Witnesses, this (3th day of March, 1899.
